A direct smelting process

A process for direct smelting a metalliferous feed material is disclosed. The process includes the steps of partially reducing metalliferous feed material and substantially devolatilising coal in a pre-reduction vessel and producing a partially reduced metalliferous feed material and char. The proce...

description	A process for direct smelting a metalliferous feed material is disclosed. The process includes the steps of partially reducing metalliferous feed material and substantially devolatilising coal in a pre-reduction vessel and producing a partially reduced metalliferous feed material and char. The process also includes direct smelting the partially reduced metalliferous feed material to molten metal in a direct smelting vessel using the char as a source of energy and as a reductant and post-combusting reaction gas produced in the direct smelting process with pre-heated air or oxygen-enriched air to a post-combustion level of greater than 70% to generate heat required for the direct smelting reactions and to maintain the metal in a molten state.
